Abstract: 142,904. Bohachik, C. Feb. 8, 1919. Burglar and like alarms.-A door lock is arranged to fire a blank cartridge when operated by an unauthorized person, and provision is made for throwing the firing-mechanism out of gear. The opening of the lock may also operate a distant signal. The lock bolt 18, Fig. 5, arranged on one side of a partition 27 in the casing, has an upper toothed limb 20 and is operated by a key with a prism-shaped ward adapted to engage the teeth 21. The other limb 30 of the bolt is toothed to engage pinions 32, 40 so that when the bolt is withdrawn the pinion 32 rotates an arm 33 to close an electric contact 36 and sound a distant signal. The pinion 40 drives a shaft carrying a pinion 42 gearing with a pinion 43 on the shaft 41 on which is splined a sleeve 66 carrying pinions 67, 68. The pinion 67 operates through pinions 44, 46, 48 and bevel gear 51, 52 to rock a shaft 52. carrying an arm which rocks a pivoted hammer 56 in opposition to a spring 72, which then returns it against a firing-pin 62 to fire one of several blank cartridges arranged in a rotating magazine within a housing 58 carried by the partition 27. A firing. tube 13 with the positioned cartridge extends from the housing and through the door adjacent to the key-hole. The magazine is mounted on a shaft 60 which is rotated to position the cartridges successively by a pinion 63 gearing with the pinion 68 on the sleeve 66. The firing of a cartridge can be prevented when an authorized person operates the lock by his first pushing in a knob 14 on a rod extending through the door and connected with an arm 65 on the sleeve 66, whereby the sleeve is moved against the spring 70 normally holding the arm 65 against the fixed stop 71 to disengage the pinions 67, 68 from the pinions 44, 63 driving the fire hammer and magazine respectively.

Abstract: 1,174,694. Gas turbine plant; turbines. T.W. ANDREW and J.D. YANDLE. Nov.5, 1968 [Jan.24, 1968], No.3777/68. Addition to 1,156,441. Headings F1G and F1T. In a modification of the rotary engine claimed in Specification 1,156,441, the combustion chamber 1 is offset laterally from the vertical plane through the axis of the rotor disc 3 and the disc is provided with axially spaced depressions 13, 17 forming first and second expansion stages, respectively. Ignition of the fuel/air mixture in the combustion chamber 1 is effected when a depression 12 in the disc 3 moves into alignment with the outlet port 10 of the chamber so that the disc 3 receives a driving pulse in the anti-clockwise direction. As the disc 3 rotates, the depression 13 moves into communication with port 10 to receive a further driving pulse. The leading edge of depression 13 then moves into communication with a port 14 in the stator casing 2 so that some of the gas leaves depression 13 and flows through port 14 and a passage 15 to enter the second stage depression 17 in the disc 3 through a port 16. When depression 13 moves out of alignment with port 10 a further depression 18 moves into communication with the latter and connects same with port 14 so that a blast of scavenging air supplied to the combustion chamber 1 flows through port 10 and depression 18 to scavenge both depressions 13 and 17 before leaving through an exhaust port 19 to complete the cycle. Depression 17 may be provided with a series of curved vanes 21 to assist impingement of the driving gases. The sealing ring 9 at the periphery of disc 3 and the remainder of the engine are substantially as described in the parent Specification.

Patent GB-547260-A (GB)
Title: Improvements in bus-bar protective systems
IPC: H02H3/28
Filed: 1941-03-21
Abstract: 547,260. Protective cut-out systems. BRITISH THOMSON-HOUSTON CO., Ltd. March 21, 1941, No. 3855. Convention date, March 22, 1940. [Class 38 (v)] In a protective system for busbar sections wherein the input to the bars is balanced against the output in a comparison circuit, and an additional safeguard against operation by external faults due to current-transformer saturation is provided by a relay in the neutral-to-earth connection of apparatus connected to the bars so that operation of the system depends on occurrence of an earth fault, the latter relay is arranged to discriminate between single and double line-to-earth faults and . to prevent operation by the latter, the inter-phase component of which may cause saturation and hence unwanted tripping. Since the external single line-to-earth fault current is limited by the impedence of the earth circuit, operation of the system on such earth faults is precluded, whereas, with the usual isolated-phase busbar arrangements, the possibility of a double lineto-earth fault in the busbar section is very remote. The busbar section 13 is supplied by a generator 19 and transformer 21 and feeds the circuits 27 ... 29. Current-transformer groups 37, 40 in the outgoing and supply circuits have overload coils, as 36, and earth-leakage coils, as 35, capable of tripping the associated breakers 22, 30. These breakers, together with the busbarsectionalizing breakers 15, 16, can also be tripped under control of a hand-reset relay, the coil 51 of which is in a circuit containing contacts 49, 57, controlled by relays 41, 56, respectively, in the balancing circuit and neutral-earth circuit 25 of the generator 19. The individual leakage circuits of the current-transformer groups 37, 40, and the similar groups 34 in adjacent busbar sections 12, 14, include the transformers 42, 46, 45, the parallel-connected secondaries of which supply relay coil 41, which is thus responsive to unbalance due to internal faults or to currenttransformer saturation on heavy external faults. It is shown in the Specification that only half as much current flows in the earth-circuit 25 on double as on single line-to-earth faults, hence the relay 56 is arranged to operate on a little over half the maximum earth-current that can flow in circuit 25, so providing the necessary discrimination. High-impedance, single-phase, short-circuits to earth on the section 13 would not operate relay 56, therefore such faults are disconnected after a time-delay by a low-setting relay 59 having contacts 60 in parallel with those 57. Where the busbars are not of the isolatedphase type, additional interphase fault relays may be provided. Where the resistor 26 is replaced by a reactor and the D.C. component, due to the larger time-constant of the circuit, assumes large value, relay coil 56 is supplied through a 1:1 air-gap current transformer, so as to eliminate that component, Fig. 2 (not shown).
